Nismo sticker=20hp

Sorry for asking such a dumb question, but is it safe to say that if I had Nismo 370z and replaced the factory Nismo exhaust and replaced it with another exhaust the net gain in HP would be close to no difference? |
I think the important question to ask yourself is "why would you fly with the sparrows when you could soar with the eagles?"
Same mods + same tune should generally get the cars in the same ballpark. Some claim the VVEL tuning is more aggressive on the Nismo, though I am skeptical. |
Actually, I asked a similar question in the exhaust/intake forum and didn't get an answer. Specifically, "is there a direct comparison in hp gains between the factory nismo exhaust and various aftermarket equivalents (FI, Greddy, Stillen, Berk).
Still haven't found anything concrete. Although I did find a guy who had a FI exhast that switched back to the nismo because the hp gains were "negligable" o_O At any rate, I've put the exhaust at the end of my bolt-on upgrade list behind my already installed intake, HFCs and headers. Not crazy about the exhaust note on the nismo but that's cosmetic. Stillen G3 intake already installed, berk HFCs and Stillen ceramic headers up next + uprev tune. Question though, if I decide to go with something other than the nismo exhaust after that, will I need yet another tune? |
I would get the tune after all the bolt-ons are done.

Exhaust is probably going to have to wait a while though. Doing the headers/cats is a decent chunk of change and I hear your low-end really suffers if you don't tune immediately. Right now I'm looking at around $2500 for headers/cats + install and uprev. Add a FI exhaust and that becomes 4k.
Still haven't answered my question re: HP gains between exhausts. If it's just a look/sound/feel issue, I'm not overly concerned. If you get an additional 20 hp over the factory nismo exhaust, that's a different story (hyperbole but you know what I mean). |
Also my girlfriend will kill me if I fill the house/garage with uninstalled car parts.

I think most of the HP claims are close to the same, but they can all put whatever they want. Just looking at all the exhaust FI has the least amount of bends, straighter should equal better flow. |
Right but there's the kicker. I'm surprised no one has compiled dyno results for various exhausts with a similar baseline. Exhaust note is neat but probably not worth an additional $1500

I've taken a nismo with just a cbe. xD

To get a real answer you would have to use the same car on the same dyno on the same day and swap back and forth between all of them. |
